Notes:
* This script will dd an entire disk. Make sure the auto-detected disk is correct,
or override it with --disk explicitly.
* On RHEL/Rocky/Alma/Fedora, the script will try to install xz, qemu-img and curl automatically
* On RHEL/Rocky/Alma/Fedora, the script will try to install xz, qemu-img, curl and pv automatically
if they are missing.
* All target systems use cloud-init NoCloud to inject root password, SSH keys, etc.
